DescriptionCVE.org

The Total Upkeep - WordPress Backup Plugin plus Restore & Migrate by BoldGrid plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.14.9 via the env-info.php and restore-info.json files. This makes it possible for unauthenticated attackers to find the location of back-up files and subsequently download them.

Executive ViewAI

Why It Matters

The Total Upkeep WordPress plugin contains a critical vulnerability allowing unauthenticated attackers to access backup files containing sensitive organizational data. Any WordPress site running this plugin version 1.14.9 or earlier is at immediate risk of data exposure, potentially compromising customer information, credentials, and business-critical content.

Business Impact: High

Compensating Controls

Apply vendor patch. If immediate patching is not possible: disable the plugin, implement Web Application Firewall rules to block requests to env-info.php and restore-info.json, restrict access to backup directories via .htaccess or web server configuration, and move backup storage outside the web root.
